Kidneys and Glucose Threshold at 180 mg/dL
The kidneys filter glucose from the blood and reabsorb it using special transporters.
When blood sugar reaches 180 mg/dL, these transporters can't handle all the glucose, causing excess to spill into the urine.
This leads to more frequent urination, thirst, and dehydration.
Over time, high blood sugar can damage the kidneys, but keeping blood sugar stable can prevent this.

Long-term high blood sugar can damage kidneys, raising the risk of diabetic kidney disease.
Stable blood sugar levels, diet, exercise, and regular checks can prevent kidney damage.
